Hi Aeslyn,
If you truly want to get you ears pierced you should just do. While it may be out of character for your male self, you can probably ride the short wave with a "just trying something different". Perhaps at the same time alter your clothing style slightly to go with a more "hipster" look and just tell people you wanted a change. For the most part it will most likely be a non-event and those who notice will most likely forget quickly.
Hugs
